45 Best Free Compressor VST Plugins

Here are the best free compressor VST plugins online that can be used with FL Studio, Reason, Ableton Live, and other VST supported software.

What Is A Compressor VST Plugin?

Compressors are used to reduce the volume of loud sounds or increase the volume of soft sounds by reducing or preventing large variations in amplitude.

Compressors have many uses in sound engineering, such as leveling out signal peaks and controlling dynamics.

The compressor is a vital component of any mixing engineer’s toolbox. It is used to control the dynamics of a signal by reducing the volume of loud sounds and amplifying softer sounds.

Compressors are used in mastering, live sound, instrument recording, and vocal production. They can be applied to a single track or an entire mix.

This gentle, squashy compressor is intended for use on buses, though it also works well on channels.

It has a very soft knee, with a ratio that gradually increases to hard limiting. It also has a choice between RMS-based level detection (with a window size that depends on the attack time) or a brand new peak sensing algorithm.

  • A slightly gentler transfer curve brings it (subjectively) closer to the hardware that inspired it (I still haven’t taken any measurements!).
  • Tweaked attack smoothing to make it a little more aggressive with the fastest settings.
  • Tweaked release smoothing to make it pump less with the fastest settings.
  • New peak sensing mode.
  • External sidechain inputs.
  • Left-click the meter to toggle the range between 6, 12, or 18dB
  • Right-click the meter to switch between Gain Reduction metering, or Gain change metering (which includes make-up gain).
